Hi - the opportunity space page is meant to be broad; a more specific and targeted programme thesis within that is going to come out in the coming months. I should mention that it's not just a call for technical solutions because, as you note, a lot of this is deeply rooted in social systems and requires design solutions (i.e. it's not just building more tech). But that is good feedback!
The idea that the future is architected by our choices (or lack of it) is the crux of one of the opportunity spaces at the Advanced Research and Invention Agency (ARIA) in the UK.
(full disclosure: I'm working with the programme director on helping define the funding programme, so if you're working on related problems, by all means share your thoughts on the site or by reaching out!)
